A small group of us are in the city of Le Mans for the 24hr race. Same trains and apartment as last time. We hopped off the train and knew to keep the track on our right. A few minutes later we got to an unfamiliar junction. We realized our mistake. Although keeping the tracks to the right is a good idea, it turns out there is both a north and south exit. Therefore the tracks can be on our right going in both directions. It made me think of all the signals and little tricks we use to navigate life and can still go arwy. In order to have not got confused we should have chosen the additional variable. What else are we certain of that may turn out to be incorrect.
